Heart rate (and possible other BLE) sensor support

Hi! I'm using racechrono for motocross training and apart from all technical data, it would be great to see heart rate. Of course I'm able to run another tracker to get HR logged, but this is not very convenient.I think this feature may be fun for car drivers too and really helpful for moto/bicycle riders.

Antti, is the issue generally with supporting Bluetooth Low Energy or is it about dealing with the various sensors (heart rate, etc.)?

I've built my own data acquisition module based on an Arduino (the RedBearLab BLEnd, which integrates BLE onboard). I am successfully emulating OBD-II to RaceChrono now, but to do it I had to buy an additional classic Bluetooth breakout board - at the time I didn't know that classic Bluetooth and BLE are different protocols. I'd love to get rid of that extra breakout board and go straight through BLE. Do you foresee any roadblocks to doing this in the future?

Hi Karter88, the issue is mostly about picking suitable hardware to support, find the protocol specs. The biggest difference in BLE is that there is no SPP meaning it's not a serial port like data stream, but packets. It doesn't matter much to RC internals, but ofcourse it needs separate implementation.

I can see how that would be a hassle to maintain both implementations. Apparently BLE is a major departure from classic so it's not just a drop-in replacement. Well, I look forward to whatever you can do. I just had my first track day with my new setup, so will probably have some questions in a new thread after I check the forum about OBD/RaceDAC communication.

Awesome! Cant wait to use it on the track. I already have the data in my separate Google Fit app but having it implemented in the software analysis for the sessions would be even more insightful for those turns where you know you're getting some real speed!
